Ingredients For Making Brownie Cookies From Brownie Mix

Got a box of brownie mix lurking in your pantry? You can make these easy brownie cookies! Don’t have one? What kind of person even are you?! J/K, but seriously, you’re going to want to keep at least one box on hand from now until forever…

Because the only ingredients you need for this recipe are:
  • your favorite 18-oz. brownie box mix* (mine is Ghirardelli Chocolate Supreme)
  • vegetable oil (any light flavored oil: canola, coconut, avocado, etc.)
  • and one or two eggs
  • chocolate chips or chunks are optional, but highly recommended

It almost seems too good to be true, doesn’t it! But yeah, you only need 3 simple ingredients — four if you’re a chocoholic like myself. You might also consider picking up these tools, if you don’t already have them (they will make baking ANY cookie infinitely easier):

PRO TIP: This brownie mix cookie recipe is ideal for kids that are beginner bakers! Make the process even more fun with a set of these adorable mini utensils. They’re the perfect size for small hands and just so stinking cute!! I *may* have just picked up a set for myself…

Okay, are you ready to make some brownie mix cookies now? Let’s do this!!

How To Make Cookies From Brownie Mix

Honestly, now that I’m getting ready to tell you how to make this brownie cookies recipe, I’m wondering if I should even call this a recipe, LOL. It pretty much goes like this:

  1. Dump the boxed brownie mix into a large bowl. In the case of the Ghirardelli Chocolate Supreme box brownie mix that I used, it comes with a packet of chocolate syrup. Go ahead and squeeze that in, as well. (By the way, Ghirardelli has absolutely NO idea who I am. I just happen to love, LOVE their brownie mixes!)
  2. Add 1/2 cup of your preferred vegetable oil. If you’re curious, I happen to use avocado oil for just about all of my cooking and baking, but any light flavored oil will work here. Or you can use butter — see the recipe card notes for this swap!
  3. Add one large egg — OR one large egg + one egg yolk (more on this in a moment).
  4. Now stir, stir, and stir some more. The brownie mix cookie batter is VERY thick, so you will need to do a lot of scraping to mix it all together. Which is why I adore this spoonula spatula! You can also use a hand mixer for this step, if you prefer.
  5. Chocolate lovers, if you’re adding chocolate chips or chunks, go ahead and fold them in now. I used the Private Selection 62% Cacao Dark Chocolate Chunks from Kroger, and they are SO good! Plus the square shape makes these simple & easy cookies made with brownie mix look a little more upscale.

Brownie Cookies Made With One Egg Or Two?

Okay, so it’s really one egg OR one egg plus one egg yolk, and the deciding factor is pretty much how ooey-gooey you want your brownie mix cookies recipe to turn out…

Think about what you typically reach for when faced with a freshly baked pan of brownies. Do you go for one of the outer squares with the crispy, chewy edges or choose the fudgy brownie texture of a center square? You can totally customize this brownie cookie recipe from a box to suit either choice.

Are you a chewy edges kind of brownie lover? Stick with one large egg for a crispier brownie cookie. But if you’re one of those brownie lovers that always reaches for a soft fudgy center brownie piece, add one large egg plus one egg yolk for a chewier cookie.

Tips For The Best Chocolate Brownie Cookies

So here’s the thing… Even though we’re making boxed brownie mix cookies, it doesn’t mean that we don’t want them to look bougie and beautiful, you know like they’re totally NOT from a mix.

Am I right? Well, it just so happens I have a few parting tips that make ALL the difference in turning out the best brownie mix cookies.

  • Use a medium cookie scoop to portion out the brownie batter dough. This will not only ensure that all of your cookies are the same shape and size, but it’s also the size that I tested for the bake time listed in the recipe. This size scoop equals 1.5 tablespoons, so in a pinch, that’s how many tablespoons of dough you should use per cookie. Also, these rich cookies spread quite a bit, so I recommend only portioning out 8 to a baking sheet.
  • Line your cookie sheet with parchment paper or a silicone baking mat. These cookies are fairly delicate and will stick to the pan otherwise.
  • Add a little bit of extra chocolate chips or chunks for prettier cookies. This tip works for any and every kind of cookie that contains baking chips or mix-ins! Press 2-3 chips/chunks into each dough ball after portioning them out with the scoop. The “extras” will stay on the top of the cookie while it’s baking, making for a perfect cookie that looks extra luscious. Peanut butter chips or white chocolate chips would be a delicious addition, as well!
  • Don’t over bake your cookies! These brownie mix cookies can quickly go from perfect to over baked, so it’s important to use visual cues as much as baking time. My cookies were perfectly cooked at 10 minutes in a 350 degree oven, but I would recommend starting to check them around the 9-minute mark. They’re done when they’re no longer shiny on top, even though they may still look slightly underbaked overall.
  • Don’t try to transfer these cookies to a cooling rack immediately. Let the cookies cool for 5 minutes on the baking sheet, and then you can safely move them to a wire rack.

Have I convinced you to try this ridiculously easy brownie cookie recipe, yet?

Just to quickly recap: it’s just 3 ingredients (4 if you add chocolate chips), 5 minutes to mix up and portion out, and 10 minutes to bake. And the best thing is these delicious cookies are cool enough to eat in just about 5 more minutes!

I mean, who wants to wait 45 minutes for a classic brownie recipe to bake and then another 45 minutes to an hour for the pan of brownies to cool? NOT ME!

*QUICK UPDATE January 2023: I’ve tested this recipe with a number of brownie mixes, all with excellent results. However, a number of readers have recently been sharing that they’ve had issues when using Duncan Hines Chewy Fudge Mix.
After a little research, I discovered that Duncan Hines changed the formulation for this variety roughly 9 months ago. And boy, do bakers have STRONG opinions about the change!! So I’m going to assume that the reported issues are a result of this new formula and recommend that you steer clear of it for now.

Easy Brownie Mix Cookies

Easy Brownie Mix Cookies

Yield: 22-24 brownie mix cookies
Prep Time: 5 minutes
Cook Time: 10 minutes
Additional Time: 15 minutes
Total Time: 30 minutes

This quick & easy brownie mix cookies recipe turns out deliciously fudgy and chewy brownie cookies from a boxed mix in just about 15 minutes! With just 3 ingredients, this easy cookie recipe is ideal for beginner bakers (and busy moms)...



  1. In a large mixing bowl, combine the brownie mix, oil, and egg (or egg + egg yolk). Note that the batter will be very thick. Fold in the chocolate chips or chunks now, if desired. Set the batter aside for about 15 minutes to allow the dry ingredients to hydrate while they oven preheats.
  2. Heat oven to 350 degrees. Line a baking sheet or two with parchment paper or a silicone baking mat. 
  3. Use a medium cookie scoop to portion out the batter into 1.5-tablespoon balls onto the prepared baking sheets. The cookies will spread while baking, so I recommend only placing 8 cookies per baking sheet.
  4. Bake at 350 degrees for 9-10 minutes. My brownie cookies were perfectly cooked at 10 minutes in a 350 degree oven, but I would recommend starting to check them around the 9-minute mark. Add an extra minute as needed; however, take care not to over bake them. They’re done when they’re no longer shiny on top, even though they may still look slightly underbaked overall.
  5. Cool on the baking sheet for 5 minutes before transferring to a wire cooling rack.


*How to make brownie mix cookies with butter:

I prefer to make my brownie cookies with oil, but 1/2 cup butter can also be used. Brownie mix cookies made with butter need to be baked for about 2-3 minutes longer. My sweet spot was 13 minutes at 350 degrees.

**One egg OR one egg + one egg yolk:

Are you a crispy edges kind of brownie lover? Stick with one large egg for a crispier brownie cookie. But if that soft and chewy fudge center brownie piece is what captures your heart, add one large egg plus one egg yolk for a chewier cookie.

Storage: Store these cookies in an airtight container at room temperature for up to 5-7 days -- though I'm sure they will be gone long before that!

Thank you so much for the warning about brownie mix brands! That happened to be the brand I had. For the Duncan Hines chewy brownie mix, use one egg, 1/3 C oil, 2Tbs water, drop by and bake at 350 for 7-9 min. Let cool on cookie sheet for 1 min The Duncan Hines brownie cookie recipe comes from the cookies in the S'mores Charcutiere Board recipe on the Duncan Hines website

I used the double chocolate premium brownie mix from Aldi. Followed suggested recipe, added chunks of mint Andi’s candies. Refrigerated for 30 minutes before baking. Baked at 350 degrees for 13 mins. They look perfect!

To make sure my cookies are the same size (and bake to the same degree of goodness) I use my kitchen scales and weigh them, in grams. How much do the raw brownie cookies weight at 1.5 tablespoons? Thank you.

Hi, I was wondering if this would work the same way with Betty Crocker Delights : Supreme Chocolate Chunks?

Hi Lei! I haven't tried this mix personally, but it's the same size as what I've tested in the past, so it seems like it should work just fine.
